5G Load Metric Reporting Control via Feedback Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G systems face challenges in efficiently managing load metric reporting between RAN nodes, particularly when a second network node temporarily stops reporting due to issues, leading to repeated requests from the first network node and excessive signaling, especially when nodes are in different wireless communication systems.
Innovation Solution
A method where the second network node sends a message to the first network node indicating pauses, resumptions, or changes in measurement reporting, including reasons and durations, allowing the first network node to adjust its requests and reducing unnecessary signaling by waiting for resumed reports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second network node stops sending measurements due to temporary issues, then the first network node receives incomplete load metric data, but the first network node sends repeated requests causing excessive signaling
Solution Approach 1:
The second network node sends a feedback message to the first network node indicating that measurement reporting is temporarily stopped due to internal issues. This feedback mechanism allows the first network node to understand the situation without sending repeated requests, thereby reducing excessive signaling while maintaining data completeness expectations.
Solution Approach 2:
The second network node proactively notifies the first network node in advance about the temporary stop of measurement reporting. This preliminary action prevents the first network node from sending repeated requests, reducing signaling overhead before the issue resolves.
2Loss of information
If the first network node sends repeated requests to resume measurements, then load metric data availability improves, but signaling load increases
Solution Approach 1:
The second network node provides feedback information about the status of measurement reporting to the first network node. This feedback eliminates the need for repeated requests from the first network node, maintaining data availability expectations while reducing signaling load.
Solution Approach 2:
The second network node autonomously manages its measurement reporting status and notifies the first network node accordingly. This self-service approach eliminates the need for the first network node to repeatedly request resumption, reducing signaling overhead.
3Use of energy by moving object
If measurements are stopped temporarily, then network node resource consumption decreases, but measurement reporting reliability deteriorates
Solution Approach 1:
The second network node proactively notifies the first network node about the temporary stop of measurements before resources are fully consumed. This preliminary notification allows the first network node to adjust expectations and reduce signaling, while the second network node resumes reporting once resources are available.
Solution Approach 2:
The second network node sends feedback information about its resource status and measurement reporting capability to the first network node. This feedback mechanism allows the system to dynamically adjust measurement reporting based on actual resource consumption, balancing reliability with resource efficiency.

AI summary
A method is disclosed that is performed by a first network node in communication with a second network node. The second network node has been requested or is being requested to send measurements and/or predictions available at the second network node to the first network node. The method comprises receiving, from the second network node, a first message comprising a first indication that sending of measurements and/or predictions from the second network node to the first network node is to be paused, delayed, resumed, or stopped. Also disclosed are a method performed by a second network node, and first and second network nodes.
